Jeeves Consumer Services AC Technician Interview Questions, Process, and Tips

The number of sensors in an inverter AC can vary depending on the model and brand.

• The number of sensors in an inverter AC typically ranges from 3 to 5.

• Sensors in an inverter AC can include temperature sensors, humidity sensors, and pressure sensors.

• Some high-end inverter AC models may have additional sensors for more precise control and energy efficiency.

The resistance of a circuit is measured in ohms.

• Resistance is measured in ohms (Ω)

• Ohm's Law states that V = I * R, where V is voltage, I is current, and R is resistance

• Higher resistance means less current flow in a circuit

• Resistance can be calculated using the formula R = V / I

The sensor voltage can vary depending on the type of sensor and its application.

• Sensor voltage can range from millivolts to volts depending on the sensor type.

• It is important to refer to the sensor datasheet for specific voltage requirements.

• Some sensors may require a specific voltage input for accurate readings.

• Sensor voltage may also be influenced by external factors such as temperature and humidity.

Common refrigerant gases used in refrigerators are R-134a and R-600a.

• R-134a is a hydrofluorocarbon (HFC) refrigerant with a global warming potential of 1430.

• R-600a is a hydrocarbon refrigerant with a global warming potential of 3.

Neutral wire carries current back to the source and is at 0 volts, while earthing wire is used for safety and is at 0 volts under normal conditions.

• Neutral wire carries current back to the source and is at 0 volts.

• Earthing wire is used for safety and is at 0 volts under normal conditions.

• Voltage on neutral and earthing wires should ideally be 0 volts to ensure proper functioning and safety of electrical systems.
